8.ADDITIONAL COMMENTS:

Nineteen hours before, fog made a observation of Iszak impossible.
This evening, observation of Anahita took place some minutes
before fog occurred again (humidity 93%).
I could see the Asteroid clear separated from the star until 18:57.
Due the wet air Anahita was not seen separated clear again until 19:09.
Between this times a drop of 0.9mag was visual not discernible.
